TIME-CONTROLLED OPERATING MECHLHISI.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed June 12, 1916. Serial No. 1oa,aoo.

To all whom it may concern:

. Be it known that I, WILLIAM J. KAMUF, a citizen of the United States,residing at Joplin, in the county of Jasper and State of Missouri, haveinvented certain new and useful Improvements in Time-ControlledOperating Mechanisms, of which the following is a specification,reference being bad therein to the accompanying drawing.

The invention relates to means whereby an operating mechanism may bepermitted or caused to function at a predetern'iined time, and itpertains particularly to a mechanism for causing an electric switch to.be thrown at a certain time upon operation of the alarm mechanism orequivalent part of a time-piece. It particularly is adapted for use inbreaking the electric-lighting circuit, and thus extinguishing thelights, of showwindows, stores, and other places where it is desired todiscontinue illumination at night without the necessity of having manualac cess to the light-controlling part for that purpose.

It is an object of the invention so to arrange a timepiece inassociation with a switch-throwing or other operating mechanism that thelatter will be permitted to operate upon movement of the alarm-winding,or equivalent operating, shaft of a timepiece, and another object of theinvention is to provide means whereby action of such a shaft isdiscontinued immediately upon completion of the switch-throwing or otheroperation.

\Vhen read in connection with the description herein. the details ofconstruction and arrangement of parts contemplated by the invention willbe apparent from the ac companying drawing, forming part hereof, whereinan embodiment of the invention, as applied. to anelecti-ic-switch-operating mechanism, is disclosed, for purposes ofillustration.

Vhile the disclosures herein now are considered to exemplify apreferable cl'nbodiment of the invention. it is to be understood that,it is not the intention to be limited necessarily thereto ininterpretation of the claim. as it is obvious that alterations andmodifications within the limits of the claim can be made withoutdeparting from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views ofthe drawing, of whic Figure 1 is a perspective view, the ;time-' piecebeing omitted;

Fig. 2 is a longitudinal sectional view,

looking from the rear; and

Fig. 3 is a plan view.

Having more particular reference to the drawing, S designates a base,inthe upper portion'of which is a slot 5, which accommodates a slidablemember D held within the slot by plates 4 secured to the base.

At one end the member D extends upwardly from the slot and carries a'pin 9 having a trigger 8 extending therefrom, the arrangement being suchthat the trigger is pivotally mounted. A standard 7 mounted on the basehas an aperture arranged to receive the free end portion, of thetrigger. Plates orthe like 6 are secured to the sides of the base atopposite places intermediately of the ends of the base and project abovethe upper plane of the base, and a shaft 14 is journaled in theseplates. This shaft carries.

a coil-spring 11 having an end secured to the base and including sideextensions 10 and a cross-piece lOforming a loop exten sion of thespring. The cross piece 10 is arranged to be brought under the trigger,-

whereupon the latter is engaged with the aperture of the standard 7, andthe tension of the spring is such that it has a tendency, when released,to swing or snap the loop from the trigger and down-against the base atthe opposite side of the shaft 1'4. Thus,

after the spring has been placed under restraint of the trigger, uponsliding movement of member D the triggeris released from member 7 andthe loop swingsor snaps over to the other side. During this movement itengages and moves any suitable electric switch. or other member that itis desired shall be operated, at apredetermined I time.

In order to release the trigger and permit operation of the spring atthe desired time, a timepiece, such as an alarn1clock,

is'secured by a band -A to the base at a place outside of the scope ofoperation of the spring. The clock has an alarm-winding shaftywhichconstitutes the operating- .shaft of the apparatus, and this shaft has across-piece C, of usual form, projecting laterally therefrom at its end,for use m winding the alarm mechanism. The elect:

also has a lever 2, which is shittable from one position to another topermit the alarm ineclianisi to operate or to keep it silent,the'positnns of the lever being indicated by the words Silent and Alarm,as is common in such clocks. The winding-shaft rotates in a directionopposite to that of winding while the alarm mechanism is in alarming;operation.

The slide member D has extending. up 'Wardly from its end portionopposite to the trigger an area D positioned to be engaged by thecross-piece or projection C of the winding and operating shaft andthereby to more theolide member and to release the trigger as that shaftrotates while the alarm mechanism is in operation. In order that,

' when the arm D. is moved and the trigger 1s released and theoperating-spring 18 permitted to function, the alarm mechanism may bestopped and thus the necessity of entirely rewmding the mechanism forthe neat operation avoided the arm D has extending from its upper end acurved portion it lying outside of the line of rotation of theorem-pieceC and terminating in a hook portion it that engages the alarmlerer -i[heparts are so proportioned and arranged that, when they are in thepositions they have when the trigger is set, the lever 2 may be moved toAlarm. in order to permit that movement of the slide necessar to set thetri er the crossniece C should he set by turning the winding shaft sothat it is not in contact With the arm D. lli hen the alarm mechanismoperates at the predetermined time for which it has been set, thecrosspieoe or nroiection C will push thelarm D and. thereby more theslide I) and release the trigger,

and. during this movement of the arm itshook portion B will shift thelever 2 to @ilent and stop operation of the alarm mechanism after thetrigger is released.

In order to hold the arm D away from the crosspiece or projection C ofthe winding and operatingshaft while the alarm mechanism is beingrewound and thus not interfere with that operation, a coil-spring 8 isattached to that arm and to the base. i ihile the power of this springis sufficient to hold the arm D and slide D in retracted position whenthe trigger is not set, it is not snii'icient to \vithdrmv the triggerwhen it is holding the opeatiug-spring, and, therefore, it is no liableto withdraw the trigger and release operating spring at an undesiredtime.

Having thus described any invention, what I claim as newgmd desire tosecure by Letters Patent, is-

The combination, with a time-piece havin an alarm mechanism thatincludes a lever arranged to throw said mechanism into and out of acondition wherein it is sus- WM; J. KAMUF.
